Using Elysia in Node.js

After v1.1.11

Elysia now supports running on Node.js natively without needing Hono as a wrapper, using @elysiajs/node (which is, in turn, based on @hono/node-server) with { adapter: node() }.

import { Elysia, t } from 'elysia'
import { node } from '@elysiajs/node'

const port = +process.env.PORT! || 3000
const app = new Elysia({ adapter: node() })
  .get('/', 'Hello Elysia')
  .get('/user/:id', ({ params: { id } }) => id)
  .post('/form', ({ body }) => body)
  .listen(port)

console.log(`🦊 Elysia is running at port ${port}`)

The instructions for before v1.1.11 are still kept below for reference.

Before v1.1.11

tl;dr: Mount Elysia onto Hono and run using tsx. Also available on StackBlitz.

import { Elysia, t } from 'elysia'
import { serve } from '@hono/node-server'
import { Hono } from 'hono'
import { logger } from 'hono/logger'

const app = new Elysia()
  .get('/', 'Hello Elysia')
  .get('/user/:id', ({ params: { id } }) => id)
  .post('/form', ({ body }) => body)

serve(
  {
    fetch: new Hono().use(logger()).mount('/', app.fetch).fetch,
    port: +process.env.PORT! || 3000,
  },
  (info) => console.log(`http://${info.address}:${info.port}`)
)

# Run the app
tsx app.ts

# Run the app in watch mode, restarting on file changes
tsx watch app.ts
